vanadium-bearing titanomagnetite; blast furnace smelting; intensified technology
It was very difficult for the smelting of vanadium-bearing titanomagnetite by blast furnace because the content of TiO(2) of blast furnace slag could amount to 20%-25%. After long term development and continuous improvement, special intensified smelting technologies for vanadium-bearing titanomagnetite by blast furnace were obtained and improved gradually. With the improvement of beneficiated material level and equipment level, smelting intensity has been increased gradually and the highest comprehensive smelting intensity reached 1.45 t/(m(3) . d). Technical-economic indexes of blast furnace have also been increased remarkably. The highest utilization coefficient exceeded 2.7 t/(m(3) . d) on the condition that: the burden grade was only about 50%.
